Figure 8
The influence of the initial concentration of heavy metals on the removal rate and adsorption amount of Pb2+ (a) and Cd2+ (b). Adsorption conditions: IP4 dosage: 0.05 g; adsorption time: 60 min; adsorption temperature: 25°C; agitation speed: 180 rpm; initial Cd2+ concentration: 25-200 mg/L; and initial Pb2+ concentration: 50-250 mg/L.
